In this video, I did try to explain what is the logic behind the script that can calculate the total length for different MEP installations even when we have in the selection of elements fittings and accessories.
The script will have an error in the calculation because of the approximation of the elbow fittings. The presented script will always have a higher value because of that approximation and the overall error should not be more than 5%.
Please make sure that before you start using this script that you back up your existing project model.
Also, if you want to download this (and all other scripts) with my sample files please visit the Shop page.
The script uses the following Dynamo packages: MEPover v.2020.6.2 spring nodes v.204.1.0
